Slice the oyster mushrooms into halves or thirds, depending on their size. Sauté them over medium-high heat in a skillet with a drizzle of olive oil for about 10 minutes, until golden and their water has evaporated.

Deglaze the pan with white wine and let it evaporate. Set aside.

Cook the conchiglioni in a large pot of boiling water according to package instructions, aiming for just beyond al dente. Drain and set aside.

Meanwhile, prepare the garlic-parsley butter: blend the shallot, garlic, and parsley in a food processor until finely chopped. Add softened butter, salt, and pepper, and blend until smooth.

Preheat your oven to 375°F (190°C).

Stuff each pasta shell with one or two pieces of oyster mushroom. Arrange the shells in an ovenproof dish and generously top each one with the garlic-parsley butter.

Bake for 12-15 minutes, or until the butter melts and flavors the mushrooms.

Serve immediately for maximum flavor and texture.

This vegetarian recipe is a celebration of bold flavors and creativity, bringing joy to your festive meals.
